GeForce GTX 260M SLI is a solution of two GeForce GTX 260M put together using NVIDIA'S SLI technology. Check the page of GeForce GTX 260M to know more about its chip. As usual, SLI relies a lot on proper driver support and may suffer from micro-stuttering in lower frame rates (below 30). Benchmarks indicate the performance is overall, up to X% better than a single GeForce GTX 260M performing by itself but at times (depending whether or not the 3D game supports SLI or in the graphics driver) it performed worse than a single GeForce GTX 260M. Most demanding games will run at high settings with very fluent frame rates (45+).
